The reason the dog is in the avatar is because after pushing 50 years, that dog is the best dang dog I've ever had the pleasure of training and getting to know. She was shot at under a trailer and left to die with her puppies. She opened my eyes to the sterotype and beliefs I once held about bully breeds and I came to the conclusion I was wrong (and yes, since then I've worked with other "bully breeds" and still come to that same conclusion about myself being wrong).
I do have to laugh how some automatically think that owning a bully breed somehow implies "toughness", but I can see that same line of thinking with gun owners.
Ultimately, the more powerful a dog is, the more dangerous they can be given circumstances. Likewise, the more "firepower" a gun posesses, the more "dangerous" it can considered to be. Guess what, they're coming after those guns, just like people are coming after dogs.
On a sidenote, what I found interesting was I really tried to find a home for the dog in my avatar after I felt comfortable with her (after about a year), but you should of seen the people who wanted her. Actually kind of sad. Then again, even for a 5lb dog we'd do a home visit to ensure of the surroundings (and people fall over dead when you do a home visit "when it's just a dog") and with a bully breed, the requirements go up 10 fold (and yes, due to their strength and possible tendencies if not cared for properly).
Then again, when I sell a gun face to face, I require a permit from the buyer be it a sidearm or rifle.
